Swing/AWT/SWT :: Replacing Old With New Data When Submit Button Clicked For Second Time
Mar 11, 2014
I have created a gui which accepts username in the text field and once clicking on submit button it fetches user details and throws it on gui via JTable.
But when i click submit for the second time using different username the background process goes well and good the vector that i pass to jtable changes with new data but the values in gui still contain the old data.
I'm trying to right a GUI in swing, and as part of my program, I want to open a secondary window out of the main window when a mouse clicks on the main window. Then, once I click a button on the secondary window, I want that window to close and submit data to the main window (like an info form). I have almost figured out how to do this, except for one problem. By putting a variable inside my form window called "ready," and then in my main window running a loop that constantly checks if ready is true and doesn't proceed until its true, I can create the form window, modify the values in it (currently just one value called "difficulty" that's modified by a jSlider), and then when i click the "begin" button, ready is changed to true, the form window closes, and the main window can proceed. However, when I try to put the while loop checking the ready variable inside a mouseClicked method in the main window, the form window freezes when it opens, and you can't see any of its content or modify it in any way (you can't even close it).
Here is my code:
//form window class import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class formWindow extends JFrame { private JTextField instructions1;
The class does get compiled but the submit button doesn't work?
/** * Orchestration class for Account */ import java.awt.*; //Importing the java.awt.* class import java.awt.event.*;//Importing the java.awt.event.* class import javax.swing.*;//Importing the javax.swing. class public class AccountDemo extends JFrame { /// initializes the variables in the container
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.
I have a JButton with a .PNG icon on it. I want to get that button click in actionPerformed Method but Jbutton have no Label... How i will know that which button clicked?
I want to create a online examination system.i want to know to how to get questions 1 by 1 on the same jsp page and on clicking the submit button the result should be saved in database.
im trying to play a sound when button is clicked. here is the following code
InputStream in; try { in = new FileInputStream(new File("failure1.wav")); AudioStream audios = new AudioStream(in); AudioPlayer.player.start(audios); } catch (Exception e) { }
just wondering why it does load;
i do get the warning
warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioPlayer is internal proprietary API and may be removed in a future release AudioPlayer.player.start(audios);
Okay i have done some research and have found that when using the JOptionPane, when the cancel or x button is clicked, the value is returned as null for the particular JOptionPane. It does not seem to work when I try to code it though, I have tried the following:
Java Code:
public static int getBoardType() { int boardType = 0; String boardInput; boardInput = JOptionPane.showInputDialog(null, "Enter 1 (LongBoard), 2 (Shortboard), or 3 (BoogieBoard)." , "Dwelling Type", JOptionPane.QUESTION_MESSAGE);
[Code] ....
If the "X" button or the Cancel button does in fact return a null value, why is the way I have this set up not working?

I am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file

I have written a program student record system but can not save data to view or submit record. Able to run the program but failed to submit record or view pre-submitted records.
I'm working on a memory game project on Khan and I'm stuck. Right now my game works by matching 2 of the same image. However, my professor wants me to add a button that allows 4 images to be paired at the same time. Right now, there are 20 images total but half of them are duplicates so that they have a match. My issue with this button is that I'm not sure how to make 5 groups of 4 of the same image. So rather than 10 different images, there will be only 5. (Still a total of 20 because every image has duplicates) My professor told me that a hint is to use a boolean variable called quadButton and work from there. URL...
I'm working on a spreadsheet-like table and I was able to set it so that it would highlight the first cell in the relevant row(titled 1,2,3.. etc) when a cell is clicked. (Just like in MS Excel - preview attached) Now I want to do the same to the column header(i.e. A,B,C,D....etc) . How can I do it?
private void formWindowOpened(java.awt.event.WindowEvent evt) { setLocationRelativeTo(null); int rowNum = sheet.getRowCount(); for(int i=0; i<rowNum; i++){ sheet.setValueAt(i+1, i, 0);
I am working on a simple app that should emulate a desktop with some icons that you can drag around. I was instructed to use the MouseListener and MouseMotionListener. The icons should drag starting at the point where the mouse originally clicked down on it (ie not dragging from the top right corner).
I am drawing my icons to a jpanel, and I seem to be having two problems:The hitboxes are offThe icon is being dragged from the top right corner, despite having setup up a mouse offset at the beginning of the drag..Here are the relevant classes, the Desktop.draw() method is being called from my DrawPanel
import java.awt.*; import javax.swing.*; import java.awt.event.*; public class Desktop implements MouseListener, MouseMotionListener{ static DesktopIcon[] icons;
I am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
